    The InVEST model and PLUS model were coupled to calculate the water conservation amount in Shaanxi Province from 2000 to 2020 and predict the water conservation amount under land use changes in the future in 2030. The results indicate that the average water conservation amount in Shaanxi Province from 2000 to 2020 was 132.25mm, with a spatial distribution characteristic of gradually increasing water conservation amount from north to south.From the perspective of vegetation types,forest land is the main body of water conservation in Shaanxi Province. The average annual water conservation amount is 199.55×108m3. From the administrative region, Ankang City (308.96mm) has the largest water conservation amount. The total amount of water source conservation in 2030 is 285.16×108m3,8.68×108m3 less than in 2020..
